Abstract: For the oxydizing colouration of the hair is used, as a coupling compound, at least one (1)-(ss-hydroxy-alkyl)-(2,4)-diamino-benzen of the general formula:  (FORMULA)  wherein R is a hydrogen atom, a methyl or ethyl group, and also the mineral or organic form thereof. Such preparations contains the coupling compound with a concentration from 0.01 to 4.0% approximately by weight and in admixture with the usual compounds allowing the development of the colouration and optionnally the usual coupling compounds. When mixed with the compounds allowing the development of the colouration, say the (1,4)-(diamino-benzene) and its derivatives, the said (1)-(ss-hydroxy-alkyle)-(2,4)-(diamino-benzene) allow to obtain relatively cold shades, of a deep blue without mixture of red. Furthermore, it is possible to obtain natural ash grey shades, as well as dark shades, particularly dark blue shades.

Abstract: The heating of submersible hulls, diving suits and other underwater equipment usually involves use of electrical batteries. However, in cold water operations these electrical batteries prove quite inadequate for the task. The invention provides for a self-contained heating system involving the bringing together in a submerged reaction zone (15) of substances capable of reacting together exothermically. Preferably one of the substances is a metal e.g. aluminium in ingot form and the other substance is an aqueous solution of sodium hydroxide and is fed to the ingots (14) of aluminium. The invention embraces also an apparatus for carrying out the reaction and transferring the heat generated.

Abstract: A component consisting of two coupled PTC thermistors with the first thermistor having a lower cold resistance than the second thermistor and the first thermistor having a higher resistance at the operating temperature than the second thermistor. According to the invention, the electric connection to the second thermistor is made directly by solely mechanical contacts to the surface of the ceramic thermistor body. This means a considerable simplification during manufacture, as the second thermistor need not be provided with electrode layers.

Abstract: A ski-binding for all modes of ski-ing is provided whereby, when the skier's weight is on the ski, relative lateral movement, both angular and translational, between boot and ski is prevented by means of the coupling underfoot of:- 
One or more central longitudinal downward projections from the underface of the boot engaging within a matching longitudinal groove in the top surface of the ski parallel to the longitudinal axis of the ski. 
or, conversely, A central longitudinal upward projection from the ski top engaging within a matching longitudinal groove in the underface of a thickened sole and heel of the boot. 
     The boot may be attached to the ski by a hinge connected at or near the toe of the boot, which locates the boot fore and aft, permits the boot to pivot up through about 90° and affords the means to provide pull and push for traction and propulsion and the means for lifting the ski in jump and kickturns. 
     For Downhill Racing a simple heel latch can be added to ensure that during airborne spells, when aerodynamic forces tend to lift the ski tip, the rear of the ski does not consequently drop and thereby relay the lateral constraint.
